Capturing Screenshot from Current level and past it to the Widget.

When I make SaveGame file I need to make screenshot to snap it in to the LoadGame widget as thumbnail. What Blueprint nodes may solve this task?

Additional questions:

  1. When I tryed yse “Take High Res Screensot” that not working in to the “Standalone Game”, and work in the “New Editor Window”, but it captured screenshot of the editor view - not in game window view!
  2. When I tryed to use “Execute Console Command” node and typed “Shot” It made correct screenshot, but that node dont give the reference to the created file to use that furter.
  3. When I tryed to use node “Download Image” to insert texture file to the widgrt image brush - it doesnt work.
